Keeping cursor in a TextBox?

I have a couple of TextBox that require a numeric value. What is the correct flow of events to make sure that a TB cannot advance to another control without a valid value?

Hi BlakeMcKenna;

For the TextBox you wish to check to see if the value is numeric use the Validating event handler as shown below. Warning once you enter the text box you will not be allowed to leave unless a numeric value is entered into it or you place logic in here to allow differently.
Private Sub TextBox1_Validating(sender As Object, e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating

    If Not IsNumeric(TextBox1.Text) Then
        e.Cancel = True
        MessageBox.Show("Value must be numeric, please correct. You will NOT be allowed to continue unless corrected.")
    End If

End Sub
